What Is a Cloud PBX and How Is It Different?
Guide · June 27, 2026 · 4 min read
What a cloud PBX is, how it differs from a physical phone system, and what it gives a business. A plain explanation.
A cloud PBX moves your business phone system off a physical box and onto a service running over the internet. Extensions, call routing, voice menus and recording all work in the cloud, with no hardware to buy.
How it differs from a traditional system
- No hardware: no expensive switchboard installed at the office.
- Works anywhere: staff connect from the office, home or the field.
- Easy to grow: adding an extension takes minutes, with no engineer visit.
- No maintenance: updates and upkeep sit with the provider.
What a cloud PBX gives you
- Multi-line answering and call routing
- Extensions and voice menus (IVR)
- Call recording and reporting
- Bring your own number (BYON) — keep the number you already have
Where it gets interesting: adding AI
A cloud PBX shows its real value when it is paired with an AI receptionist: the call lands on the cloud PBX, is routed to the AI, and the assistant talks, books and transfers to the right extension when needed.
How OZVA approaches it
OZVA offers the cloud PBX and the AI receptionist in one package. If you already have a phone system, OZVA connects the AI as an extension; if you do not, the AI + PBX package covers both. Either way you bring your own number and carrier (BYON).
